There is a huge list of brands that have manufactured indoor air purifiers. You must understand what you want from your purifier. Only consider those features before purchasing to avoid overspending. It will also enable you to avoid some performance and usability issues later on.
First of all, you need to consider various types of indoor air purifiers.
Types of Indoor Air Purifiers
There are four different types of indoor air purifiers. These are briefly described as follows:
This filtration system type is the gold standard in indoor air purification. It involves a highly dense filter paper. This paper can trap airborne contaminants with a good effect. You need to trust and buy those indoor air purifiers that come with HEPA certification. There will be a label saying True HEPA Filter. It will be certified to get rid of 99.97% of microscopic contaminants with ease. However, you do need to replace these filters frequently. This filtration system can remove particles of 0.3 microns.
This air cleaning technology works by releasing a cloud of ions (charged) within the air. This cloud is capable to latch onto the airborne contaminants. These particles then fall onto the nearby surfaces and floor. Some of these indoor air purifiers come with an electrostatic plate for the collection of these particles. This filtrations system can conveniently remove particles of up to 0.01 microns.
In this filtration system, the manufacturers use a specific carbon-activated filter. It contains numerous tiny pores that are capable to absorb. These pores make a large surface and can trap odors, fumes, and gases. This filter is not an ideal option for eradicating particles that are injurious for health. In fact, it is more suitable for eliminating the particles that cause smells.
This technology uses an invisible light to attract various pollutants. There is no physical filter involved in this technology. The light is present within the air purifier and is not released in the room. These filtration systems have a UV-C band of ultraviolet. However, this band is not harmful to humans. This light destroys the DNA structure of bacteria and viruses and keeps the air clean for you to breathe.
CADR & ACH Rating
When you want to purchase an indoor air purifier there are some important ratings that you need to consider. These include ACH and CADR ratings. The ACH means Air Changes per Hour. It tells you that how many times an indoor air purifier can exchange the air in your room with the fresh air outside in an hour. The common ACH ratings for an indoor air purifier include 6x or 4x etc.
On the other hand, CADR means Clean Air Delivery Rate. It tells you how well their indoor air purifier can clean the air in a specific sized room. This rating enables you to objectively compare the performance of various devices. It enables you to pick the right device for your room. You can do so according to the performance capability of the device and the size of the room it can purify.
Choosing the right size
Another aspect that you must consider before buying an indoor air purifier is the size of it. It will enable you to understand what type and capacity of a purifier will work best for your vicinity. Most people are off the view that this machine is a one-size-fits-all kind. However, you need to find the right size if you want the best performance from your purifier.
You must look for rate square footage rating of the purifier you are considering to buy. You can also compare it to the size of your room too. If your option has a rating that is either greater than or equal to your room size, then don’t hesitate to buy it.
You can calculate the square footage of your room by multiplying the length and width of your room. For example, if your room is 200 square feet then you will need a filter that will work for this square footage or more. Anything less will not be sufficient.
Considerations for placement
If you have an indoor air purifier with Carbon or HEPA filter technology then place in the open. There should be no wall or furniture near it. Its fan will replace the clean and fresh air from the outside. You don’t want to break this stream for excellent performance. On the other hand, the ionic filtration purifiers don’t use a fan because they emit ions. These systems work the best when you place in the center of your room.
There are some extra features that you need to consider. These include:
The digital controls enable the users to adjust settings with more accuracy when it comes to air quality. These are a far better option as compared to the conventional controls.
Such a filter can capture a large number of particles and it can also extend the life of the filters. You can wash these pre-filters and reuse them according to your needs and requirements.
Indicators for filter replacement
These indicators can alert you when to replace the filters when they wear out. The lights will turn on when the filter is too much clogged with various pollutants. These indicators will enable you to keep your purifier properly maintained at all times.
A programmable timer can automatically shut itself off after a specific time. You can set this time according to your needs. It will enable you to save energy and electricity cost particularly when you are not at home.
Handles and casters
A carrying handle will enable you to carry and transport your purifier to wherever you want. You can easily move it from one place to another without any issue. Casters also provide you with the same convenience of mobility.
With this nightlight, you can easily locate your purifier at night or in the dark. In this case, it is an ideal option for a bedroom or even a living place.
Remote control and mobile app
The remote control will enable you to control the device from a distance. On the other hand, a mobile app will enable you to control it even when you are not at home. With the app, you will also be able to get data on the air quality of your room.
There are various options that you can consider when buying an indoor air purifier. You can either go for a premium quality indoor air purifier or an affordable one. The important thing to keep in mind is to understand what you want from your air purifier.
You must buy a suitable machine for your space. If a machine is designed for a small room it will not work properly in the large room. You must also have a close look at the technologies that you can choose. A filter for eradicating odors and smells won’t filter dust particles. Similarly, a room that is not exposed to too much dust or dirt doesn’t need dust or dirt filtration.
